As you perhaps know, two interesting routines: jq and pdftk have been installed into Tool Labs (thanks Tim!), I just tested pdftk and it runs perfectly.

* jq is a json data parser, I found it into the doc of ia (the command line version of internetarchive python module: https://pypi.python.org/pypi/internetarchive);

* pdftk if a old but effective tool to manipulate pdf files, I need it to split & merge pages of big pdf files while uploading them from Opal into opallibriantichi new "wikisource oriented" collection of Internet archive.

If you are interested about ancient books, take a look: most of them are Italian books, but there are too Latin, French, English ancient books, sometimes with parallelel translation.
